Abstract: The Neolithic introduction of domestic cattle into Europe was followed by differential
adaptation, selection, migration and genetic isolation, leading ultimately to the emergence of specialized breeds. We have studied the differentiation of European cattle by ampliﬁed fragment length polymorphism (AFLP) ﬁngerprinting. Combining AFLP data sets from two laboratories yielded 81 biallelic polymorphic markers scored in 19–22 individual animals from 51 breeds. Model-based clustering differentiated Podolian cattle as well as French and
Alpine breeds from other European cattle. AFLP genetic distances correlated well with
microsatellite-based genetic distances calculated for the same breeds. However, the AFLP data emphasized the divergence of taurine and indicine cattle relative to the variation among European breeds and indicated an Eastern inﬂuence on Italian and Hungarian
Podolian breeds. This probably reﬂects import from the East after the original introduction
of domestic cattle into Europe. Our data suggest that Italian cattle breeds are relatively diverse at the DNA sequence level.2011-04-14T22:00:00Z
